Don't deploy your application in Jetty, deploy Jetty in your application.

按照以下步骤可以把jetty服务器嵌入到用户项目中：

1. 创建一个server
2. 添加并配置connectors
3. 添加并配置Handlers
4. 为Handlers添加并配置Servlets/Webapps
5. 启动server
6. ......(wait)

配置Handler

jetty需要一个Handler来响应请求，Handler可能会

• 检查或者修改 HTTP request.
• 产生完全的HTTP response.
• 调用其他 Handler.
• 选择一个或多个Handler来调用.

现在写一个最简单的HelloHandler，代码如下：

public class HelloHandler extends AbstractHandler
{
    public void handle(String target,
                       Request baseRequest,
                       HttpServletRequest request,
                       HttpServletResponse response)
        throws IOException, ServletException
    {
        response.setContentType("text/html;charset=utf-8");
        response.setStatus(HttpServletResponse.SC_OK);
        baseRequest.setHandled(true);
        response.getWriter().println("<h1>Hello World</h1>");
    }
}

代码中参数解析：

• target–请求的目的地，可能是个URI或者命名调度器中的一个名称(a name from a named dispatcher).
• baseRequest–jetty易变的请求对象，常常是不封装的(unwrapped).
• request–请求对象，常常是封装的(wrapped).
• response–响应,常常是封装的(wrapped).

The handler sets the response status, content-type and marks the request as handled before it generates the body of the response using a writer.
handler在响应以前设置响应状态、内容类型、标记请求，响应过程就是向页面写入字符“<h1>Hello World</h1>”
驱动代码如下：

public static void main(String[] args) throws Exception
{
    Server server = new Server(8080);
    server.setHandler(new HelloHandler());
 
    server.start();
    server.join();
}
